Old tow rig...

[marks86]

I came across a C20 with 3.73 14 , had a HD TH350 with vented pan. 4.10 are great if you can get the overdrive. NV4500 is a great swap

I did nv4500 swap when I put the cummins in, also swapped out the 4.56 for 3.73 truck runs up the highway nice and smooth

Np205?

[marks86]

Nope, still have the 208, no issues. Knock on wood

Adapter?, K30 with 8" rails?

[marks86]

I had the transmission custom built with a dodge input shaft, to a Chevy output, so the np208 bolts right up with the stock adaptor

The 700 is a good transmission when built to hold it. Get some taller tires now

I'm running 285/75's. Tall enough for me!

M1008? Nice!

8" or 6" rails ?

8" or 6" rails ?

I'm assuming you mean bed length? its an 8ft bed

Nope, K30 rails are taller and heavy gauge. I've seen 30 with 20 frames.

I’ve seen piles of 10’s and 20’s with dana 60’s under the front. We didn’t get many K30’s down here. About the only ones you see are ex-mil!

Oic, no it’s a 1/2 Ton frame, I built the truck starting with a 86 k10 then bought a m1028 with a ruined body, but had 28k miles and took all the good parts

Real K30 are getting tough to find. K30 Subs even more.
